1. PSYCHOMETRIC ANALYSIS OF WAEC AND NECO PRACTICAL PHYSICS TESTS USING PARTIAL CREDIT MODEL
ABSTRACT
The purpose of the study was to analyse the psychometric qualities of practical physics questions of West African Examination Council and National Examinations Council using the Partial Credit Model (PCM). The objectives of the study were specifically to evalua...
2. A Review of Dimensionality Reduction Methods and Their Applications
ABSTRACT
In the world we live in today, the reduction in data generally has seen a great rise. This is because of the numerous advantages that comes with working with smaller efficient data instead of the original large dataset. With this analogy, we can adopt Dimensionality reduction i...
3. CATEGORIZATION OF DATA USING HIERARCHICAL CLUSTERING
ABSTRACT
In this project, we shall implement the hierarchical clustering algorithm and apply it to various data sets such as the weather data set, the student data set, and the patient data set. We shall then reduce these datasets using the following dimensionality reduction approaches:...
4. Data Classification Using Various Learning Algorithms
Abstract
Dimensionality reduction provides a compact representation of an original high-dimensional data, which means the reduced data is free from any further processing and only the vital information is retained. For this reason, it is an invaluable preprocessing step before the appli...
